MJ－331 Water-soluble copper corrosion inhibitor
Applications:
The product is applicable to the chemical treatment of cooling water as copper corrosion inhibitor, especially it is applicable to refrigeration system, central air-conditioning, power house steam condenser and other system that copperiron coexisting as corrosion inhibitor, and also can be used to anti-rust liquor 、antifreeze as corrosion inhibitor.
Characteristics:
The product is composed by benzene and 3nitrogen, organic amic, additive and so on. It can dissolve with water as any proportion, and the product easily produces the thin and compact protection film on metal surface to reduce the velocity of dissolving oxygen in water, and reduce oxygen corrosion.
The product not only has good effect to restrain symmetrical corrosion for copper, but also has good effect of restrain for other metal partly corrosion including galvanic couple corrosion, pitting corrosion, welding line corrosion.
